aspirate

Scrape cells using a cell scraper and aspirate the resulting slurry into a 2.0-mL Eppendorf tube.

There is no doubt that the uncertainty about the letter H, which much defaces English in some classes of the community, is due entirely to Norman influence, for Frenchmen could not aspirate. Three words—hour, honor, heir, with compounds of them such as hourly, honourable, heirship, and the like, are quite enough to puzzle people who find H sometimes sounded, sometimes not.
